Latest Patents
Puranen's latest patents include a "Method and equipment for attenuation of oscillation in a paper machine or in a paper finishing device." This invention focuses on a method and apparatus designed to dampen vibrations in a paper machine. The apparatus features a dynamic damper that includes a weight suspended by a spring. The spring constant can be adjusted via a control device, allowing for the tuning of the natural frequency of the dynamic damper. This tuning is crucial as it aligns the damper's frequency with a multiple of the rotational frequency of the roll in the paper machine being damped.
Another significant patent is the "Method and device for changing the natural frequency of a nip roll construction in a paper or board machine." This invention provides a method and device for altering the natural frequency of a nip roll construction. It allows for the adjustment of the rigidity of one or several loading elements, such as a loading cylinder or loading beam. The design includes a cylinder with two fitted pistons, creating a work pressure space and counter-pressure spaces that enable the variation of the loading cylinder's rigidity.
